Public demo snapshot of an in-house pyRevit extension for precast concrete shop-ticket QC (37 checks / 46 checklist rows) and a standalone panel handling solver (PCI Chapter 8). - No client, job, plant or product data: knowledge layers ship as structural templates only. - Ticket QC's model-read escalation targets a LAN model server endpoint (configurable), not a cloud provider. - Built from the private development repo via tools/make_dist.py.

THREE OUTPUTS, AND WHY THE RISA ONE IS A DRAFT
|
|
----------------------------------------------
|
|
`emit_json` the intermediate structure verbatim. This is the ground
|
|
truth and the only output that claims to be complete.
|
|
`emit_csv` nodes and members as two plain tables. Any engineer can open
|
|
these, and any script can read them. No format risk at all.
|
|
`emit_risa_draft`
|
|
RISA-3D .r3d text. **DRAFT. NOT VERIFIED.**
|
|
|
|
What was established about the RISA-3D format, and from where:
|
|
|
|
RISA's own Appendix D - File Format
|
|
https://help.risa.com/risahelp/risa3d/Content/Appendices/Appendix%20D%20(3D).htm
|
|
|
|
* .r3d is plain ASCII, keyword driven, editable in Notepad.
|
|
* Data is divided into segments delimited by bracketed keyword labels:
|
|
[NODES], [MEMBERS], [PLATES], [BOUNDARY_CONDITIONS], [BASIC_LOAD_CASES],
|
|
[UNITS], [VERSION_NO], [PROGRAM_INFO], and the file opens with
|
|
[RISA-3D_INPUT_DATA].
|
|
* The record count follows the keyword label in angle brackets: `<n>`.
|
|
* Every record ends with a semicolon, except the project-description
|
|
records between [.PROJECT_DESCRIPTION] and [.END_PROJECT_DESCRIPTION].
|
|
* Labels are quoted strings. A member label may be up to 20 characters.
|
|
* A node record is "LABEL" x y z ... ;
|
|
* A member record is "LABEL" "DESIGN_LIST" "SHAPE_LABEL" iNode jNode ... ;
|
|
with later fields covering K node, rotation, section-set offset,
|
|
tension/compression, design rules, material, end releases, end offsets.
|
|
|
|
What was NOT established, and this is the reason for the word DRAFT:
|
|
|
|
The documentation designates the fields of each record by letter (a, b, c,
|
|
...) and the table that maps those letters to meanings could not be
|
|
retrieved -- the mirror that carries it returns 403, and no complete
|
|
worked example of a [NODES] or [MEMBERS] record was found in public
|
|
sources. So the field COUNT, the field ORDER, and the encoding of the
|
|
[UNITS] line are not known with confidence. Nor is which RISA version's
|
|
schema a given install expects.
|
|
|
|
Guessing them would produce a file that very plausibly opens and is
|
|
quietly wrong about which column is which -- the single worst outcome
|
|
available to this tool. So the RISA output is written with a
|
|
`.r3d.DRAFT.txt` extension. That is deliberate and is not a naming
|
|
accident: it cannot be double-clicked into RISA, and anybody who wants to
|
|
try it has to rename it, which is the moment they read the header.
|
|
|
|
To finish this properly: open any existing .r3d from this office in
|
|
Notepad, paste its [UNITS], [NODES] and [MEMBERS] segments into the repo
|
|
issue, and the emitter becomes a real one in about an hour. Until then the
|
|
CSV and the JSON are the outputs to use.
|
|
|
|
IronPython 2.7: no f-strings.
